How add additional item in RecycleView

Question

I have a horizontal list of images that I receive from api, I want to implement saving one of the items in a separate folder. How can I add an additional element to the end of my list that will have a different appearance, I want to use it as storage for the user?

My Adapter

Сlass ImagesAdapter : RecyclerView.Adapter<ImagesAdapter.ViewHolder>() {
private var images: List<Image> = ArrayList()

fun setList(newImages: List<Image>) {
    images = newImages
    notifyDataSetChanged()
}

override fun getItemCount() = images.size

override fun onBindViewHolder(holder: ViewHolder, position: Int) {
    holder.bind(images[position])
}

override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): ViewHolder {
    val view: View =
            LayoutInflater.from(parent.context).inflate(R.layout.item_images, parent, false)
    return ViewHolder(view)
}

var onItemClickListener: (Image) -> Unit = {}


inner class ViewHolder(private val viewItem: View) : RecyclerView.ViewHolder(viewItem) {

    fun bind(image: Image) {
  
        viewItem.apply {
            title.text = image.title
            setOnClickListener {
                onItemClickListener(image)
            }

            val request = ImageRequest.Builder(context)
                .data(image.imageUrl)
                .target(
                    onStart = {//todo},
                    onSuccess = { imageMini.setImageDrawable(it)},
                ).build()
            context.imageLoader.enqueue(request)
        }
    }
}

Create a generic list.
add all your existing items to that list
add your new item to the end of the list
create two types of viewtype based on instances from generic list
create two viewholders with different layouts
then on oncreateviewholder method decide which view holder to attach based on view type.
